|Eastern Bluebird, male|
When I heard scratching again, I turned the flue and heard something drop in to the main chamber. I got my flashlight and got myself ready for whatever might come rushing out at me. When I opened the door and turned my light inside this little bluebird blinked back at me. Poor little thing. I picked him up (took his photo) and put him outside where upon he promptly flew away.
All in a days work :) My hands are black.
